[0002] In current assembly line production processes, pallets are a common logistics carrier, widely used to transfer products between different workstations. However, how to achieve efficient and stable pallet transfer remains a pressing issue in current production processes.

[0003] Traditional manual pallet transfer methods are not only inefficient but also pose safety risks. With the continuous expansion of production scale and the acceleration of production pace, manual pallet transfer can no longer meet the needs of efficient production. Furthermore, due to the uncontrollable nature of manual operation, pallets are prone to collisions, falls, and other accidents during transfer, resulting in product damage or production line halts, further impacting production efficiency and quality.

[0004] In summary, how to achieve stable performance, easy operation, and convenient maintenance of automated pallet transfer equipment, and achieve efficient and stable transfer of pallets between different workstations, has become a key issue in the current automation transformation of production lines. This not only helps improve production efficiency and reduce production costs, but also enhances the safety and stability of the production line, creating greater economic benefits for enterprises.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0045] In view of the problems existing in the above-mentioned prior art, this embodiment provides a pallet transfer pulley, see Figure 1 This is a cross-sectional view of a pulley. The pulley mainly includes a platform 1, a slide rail 3 and a matching slider 4 arranged in a through slot 2 of the platform 1. The slider 4 and the slide rail 3 realize lateral movement. The slider 4 is vertically connected to a first electric cylinder 5, which realizes longitudinal movement. The width of the through slot 2 is smaller than the length or width of the pallet to be transferred to ensure that the pallet to be transferred can be placed across the through slot 2. The guide rod of the first electric cylinder 5 is connected to a transfer plate 6. In this embodiment, the transfer plate is a plate member including two transfer stations, arranged along the through slot 2. In practice, the number of transfer stations can be increased as needed to realize the transfer of pallets at more stations in one action.

[0046] It should be noted that, in order to ensure that the transfer plate 6 connected to the first electric cylinder 5 can transfer the pallet, when the first electric cylinder 5 is in a fully extended state, the transfer plate 6 is parallel to or higher than the upper surface of the platform 1.

[0047] Taking into account that when the transfer plate 6 is long, there may be an imbalance problem caused by uneven force, this embodiment provides a group of auxiliary guide mechanisms on both sides of the first electric cylinder 5 along the direction of the through groove 2, each mechanism includes an L-shaped plate 7 connected to the slider 4, which is provided with a through hole, and the mechanism also includes an auxiliary guide rod 8, one end of which is connected to the bottom of the transfer plate 6, and the other end passes through the through hole matched with it, so as to realize the smooth lifting and lowering of the transfer plate 6.

[0048] In this embodiment, the first transfer station includes a first clamping block 9 and a second clamping block 10 connected to the transfer plate 6 and arranged along the direction of the through slot 2. The first clamping block 9 and the second clamping block 10 are both perpendicular to the transfer plate 6, and the distance between them matches the width of the pallet to be transferred, and can also be slightly smaller than the width of the pallet. The second transfer station includes a first positioning block 11 and a second positioning block 12 connected to the transfer plate 6 and arranged relatively along the direction of the through slot 2, and the distance between them matches the width of the pallet to be transferred. The inclined positioning blocks can play a guiding and limiting role, ensuring that the pallet can be transferred even with a certain error.

[0049] In this embodiment, there are three processing stations arranged in sequence on the platform 1, corresponding to the three positions where the pallet appears on the platform 1, and the pallet transfer pulley is used to transfer the pallet on the processing station to the next processing station. In actual applications, the number of processing stations can be increased as needed. At the second processing station, this embodiment respectively sets a second electric cylinder 17 and a fifth positioning block on the platform 1 on both sides of the through slot 2. When the guide rod of the second electric cylinder 17 is fully extended, the distance between the end of the guide rod and the fifth positioning block matches the length of the pallet to be transferred. In addition, a first probe 15 is provided on one side of the second processing station. At the third processing station, this embodiment is provided with a third positioning block 13 and a fourth positioning block 14 respectively connected to the upper surface of the platform 1 on both sides of the through slot 2 and arranged relative to each other perpendicular to the direction of the through slot 2. The third positioning block 13 and the fourth positioning block 14 are inclined outward and the distance between the two matches the length of the pallet to be transferred. In addition, a second probe 16 is provided on one side of the third processing station. In a specific application scenario, an empty pallet is placed on the first processing station manually or by equipment, products are placed in the pallet by humans or other equipment on the second processing station, and pallets filled with products are palletized by humans or other equipment on the third processing station.

[0050] In this embodiment, the first electric cylinder 5 and the second electric cylinder 17 are implemented by commercially available products, and the first probe 15 and the second probe 16 can be implemented by commercially available photoelectric probes, infrared probes or ultrasonic probes. The slide rail 3 and the slider 4 are implemented by commercially available products.

[0051] See also Figure 2-Figure 6 Schematic diagram of the five positions of the pallet transfer device during a transfer process.

[0052] See also Figure 2 Before transfer, a pallet is placed at each of the first and second processing stations. Slide rails 3, sliders 4, and the first electric cylinder 5 drive the transfer plate 6 to move below the pallet. The first and second transfer stations are located below the first and second processing stations, respectively. The second electric cylinder 17 extends, causing both sides of the second pallet to abut against the fifth positioning block 18 and the guide rod ends of the second electric cylinder 17, respectively, to achieve positioning.

[0053] See also Figure 3 When the first probe 15 detects a pallet, the first electric cylinder 5 lifts the transfer plate 6, the first and second clamping blocks 9 and 10 mate with one pallet, the first and second fixing blocks 11 and 12 mate with the other pallet, and the pallet loses contact with the platform 1. The second electric cylinder 17 retracts.

[0054] See also Figure 4 , the slide rail 3 and the slider 4 drive the transfer plate 6 to move horizontally, so that the two pallets reach the second processing station and the third processing station respectively.

[0055] See also Figure 5 After the second probe 16 detects the pallet, the first electric cylinder 5 retracts, driving the transfer plate 6 downward, and the pallet regains contact with the platform 1. The second electric cylinder 17 extends, causing the two sides of the first pallet to abut against the fifth positioning block 18 and the guide rod end of the second electric cylinder 17, respectively, to achieve positioning.

[0056] See also Figure 6 , the slide rail 3 and the slider 4 drive the transfer plate 6 to move horizontally and return to its original position, completing a transfer action.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
